Show hintHide hint
Consider how a rubber band changes length when pulled.
3Question 3.
What does strain rate measure?
- Volume change
- Rate of deformation
- Mass change
Show hintHide hint
Consider how forces are applied to fluids.
4Question 4.
True or False: Linear strain is concerned with the change in angle.
- True
- False
Show hintHide hint
Think about how stretching happens compared to how sliding occurs.
Question 5.
A hydraulic cylinder experiences linear strain of 0.02 m and shear strain of 0.01 radians. Calculate the new length if the original was 2 m.
Show hintHide hint
Consider what strain does to an object's length.
Question 6.
